A relatively large reddish-brown squashbug, distinguished from the commoner Coreus marginatus
by the narrower abdomen and more pointed lateral extremities of
the pronotum. Nymphs have a green abdomen.

Historically
very rare (RBD1) and known only from Box Hill in Surrey, where it feeds
on Box trees, this bug is expanding its range and now occurs widely in
the south-east of England and beyond. It is exploiting different foodplants,
and has been
found on hawthorn, buckthorn, yew and plum trees.
